You don't need the grub menu, only the Xen console. Try pressing Ctrl+a three time to switch between the dom0 input to the xen input prompt. -----Original Message----- From: Andrew Lyon [mailto:andrew.lyon@xxxxxxxxx] Sent: Friday, December 12, 2008 9:27 PM To: Aviv Grafi Cc: Jeremy Fitzhardinge; Xen-devel; Ian Campbell Subject: Re: [Xen-devel] Re: pv_ops dom0 USB fixed On Fri, Dec 12, 2008 at 7:15 PM, Aviv Grafi <aviv@xxxxxxxxxxxx> wrote: > You can use the Xen console (serial) to reboot the machine.

I added panic=5 to the linux kernel arguments which has had the desired effect, unfortunatly despite the serial console working with Xen and Linux it appears to not work with grub, I copied the grub serial config from my main workstation so I am sure the config is correct as it works on that system, but on this Dell Optiplex 755 I get no grub menu over the serial console, just the Xen & Linux dmesg, oops, and reboot, so the machine is now stuck in a rebooting loop until I get back to the office on tuesday :(. > I'm had the same ata problem two weeks ago.
